This bolt has a strength class of 8.8, with the strength class stamped on the head.
It has a regular hexagonal head and is tightened using a wrench or spanner.
It can be tightened more securely than slotted or cross recessed screws.
●Full thread = A bolt where the entire length below the head is threaded. (Generally for lengths of 30mm or less)
●Partial thread (medium bolt) = A bolt that is only threaded from the tip partway up the shank.
Partial thread length calculation (approximate guide)
L = up to 129　　　Nominal thread diameter × 2 + 6
L = 130–219　　　 Nominal thread diameter × 2 + 12
L = 220 and above　Nominal thread diameter × 2 + 25
Example: For an M10×250 partial thread bolt, since L (length) is 220 or more, the threaded portion is 10×2+25 = 45mm.

Hot-dip galvanized coating has a large film thickness, and may not be compatible with other surface finishes.
Additionally, even with the same hot-dip galvanized finish, compatibility issues may arise if purchased from different suppliers.
In such cases, we may not be able to accept returns, so please be aware of this before proceeding with your purchase.
